This invention relates to drinking or dispensing vessels such as drinking glasses, mugs, steins, pitchers, in which it is desired to maintain the liquid in the vessel at a relatively low temperature.

One object of my invention is to provide a vessel having two compartments whereby the liquid to be cooled may be kept in one compartment and cooling medium kept in the other compartmentand out of contact with liquid to be cooled.

Another object of my invention is to provide a Vessel of the foregoing character having two compartments separated by a partition, with means for cooling the entire surface of the partition between the two compartments thereby to ensure maximum cooling eciency of the vessel.

One particularv object of my invention is to provide a modified beer mug for serving beer, in which a small compartment is provided centrally Within the usual liquid containing compartment of the mug in order that the beer surrounding the auxiliary central compartment may be kept cold for a relatively long time by means of a cooling medium within the central compartment.`

Another object of my invention is to provide a drinking or dispensing vessel embodying the principle of construction of the beer mug just referred to, in which a small piece of carbon dioxide may be utilized as the cooling medium to permit the use of a relatively small auxiliary'cooling compartment Within the main compartment, with provisions for ready access to the cooling compartment for insertion of the cooling medium and for easy cleaning of the auxiliary compartment. In order to provide for cooling of a liquid in a serving glass or dispenser without immersing a cooling medium in direct contact with the liquid to-be served or dispensed, I provide an auxiliary shell to extend into the liquid containing compartment and so constructedthat the wall of the shell, which serves as apartition between the liquid containing compartment and the space or compartment contained within the auxiliary shell. The space within the auxiliary shell is then supplied with the cooling medium by means of which the heat from the liquid in the main compartment is conducted away.

The vessel I have provided is particularly adapted for use with dry ice or solid carbon (Cl. Gi-91.5)

dioxide, as the cooling medium. In order to obtain the maximum efficiency of the cooling medium, the carbon dioxide gas is caused to engage and pass along the inner surface of the-wall of the auxiliary vessel, which serves as the cooling partition between the cooling compartment and the main compartment.

One embodiment 'of my invention consisting of a drinking glass such as ordinarily used for beer, is illustrated in the accompanying drawing in which Figure lis a side elevational viewof a drinking glass to which the invention is applied; Y

Figure 2 is a vertical side view partly in elevation and'partly in section with parts broken away to show the disposition of the cooling cham.- ber within and extending up into the liquid compartment; I

Figure 3 is a plan View of the glass in Figure 1; Figure 4 is a bottom view of the glass in Figure 1; I Figure 5 is a side elevational View ofthe cup for the solid carbon dioxide; i

Figure 6 is a side elevational view of the` cork plug, and Y Figure 'I is a vertical sectional view of the cup and plug assembly. As shown in the drawing, a serving glass Ill consists of a vertical cylinder Vsubdivided into two compartments Il and l2 by a bottom partition I3. A handle Ill for the vessel is provided to permit manipulation of the glass.

In order to permit the liquid in the compartment II to be kept cooled against the warming influence of ambient temperature, an auxiliary compartment I5 is provided to receive and hold a cooling medium. The compartment I5 is provided by and within a glass receptacle I6 Vinverted and extended upward intothe main compartment II of the glass. Access to the auxiliary cooling compartment I5 is available from the bottom of the vessel I0 through the main bottom partition I3, upon which the inverted receptacle I6 is supported.

The bottom partition i3 is provided with an opening I8 through which access may be had to the cooling compartment I5. A plug or cork I 9 of the usual truncated cone shape with a tapered external surface is provided y of proper size to permit it to be snugly fitted into the opening I8 in the bottom parts of the vessel.

Plug I9 is provided with an axial passage 2| to permit a free passage for the cooling gas from the solid carbon dioxide that is used as the cooling medium. I Y y Y In order to prevent localization of the cooling effect of the carbon dioxide and in order to ensure a uniform cooling of the wall of the cooling 10 receptacle I6, a cup 22 is supported in position by the plug or cork I9 in spaced relation from the glass surface. The cup 22 consists of the cylindrical body 23 anda lower co-axial extension 24. The body portion 23 is hollowed out at one V end to provide a .recess-or cup compartment 25 for the carbon dioxide to serve as the cooling medium. The portion of the body below the cup Acompartment 25 is provided with one or more L king a cylindrical glass shell having a main body passages 26 extending through the body of the" supporter sufficiently far into the body to communicate with the longitudinal passage .21V

through the lower extension 24.`

Y When the glass vessel is'to be to .serv'eafV liquiddrink, a piece of solid carbon dioxide is placed in the recessvof the cup 22 that'is already associated with a corkas shownin Figure i7 and the entire assembled unit .is inserted into the opening .I8 in the bottom I3 of vthe vessel. VThe liquid VYto be served is then placed in the usual "30 compartment II. As lthe solid carbon dioxide becomes heated, lits gas .moves up `over the 'top edge 28 of the body cup Vand-:moves down along the innersurface of the auxillaryc'oolng chamber vessel I6'on its Away'tothe exit passages `26 '35and'2'I atthe bottom of lthe `support*and'tl'irough the support I9. f In order that Ythe gas so formed may not be trapped within the 'bottom of the rdrinking vesl sel, the lower edge 4of the vessel 29 is .provided 40 with Vone or more notches 3| through which the carbon 'dioxide gas may readily pass.

IByl means jof the construction illustrated, the cork and support for the carbon dioxidemay be readily inserted imposition for use-.or removed to permit washing of thevessel. With the construction of the cup as shown and the combined rela- Y ftionwith `the auxiliary compartment, Ethe Yentire compartment wall V.is cooled thereby ensuring *uniform cooling ofltheliquidwithin'the glass ves- 50 sel. f The provision of the pressure `relieving notches Tat the bottom edge of the vessel prevents building up of pressure by thecarbonfdioxide gas,

that Amight unduly stress 'the elementsfof 4the vessel. l Y

'-Ihe Vplug or cork I9 `is preferablymadeof rubberv so that it may be easily washed `and handled, while at the Sametime providing'a heat-insulating support vfor the cup'element 22, which may be of light metal orof molded material. K 60 A cold drink, if served `when the ambient .tem-

perature is considerably higher, Vtends lquickly .to become Warm. VIn the case of beer, the rise in temperature aifectsits flavor. When servedin a glass `of the type described, Vwith ya `small pellet 65 vof `dry .icein the cooling compartment, the cold `temperature of the liquid inthe maincompartment 'may beheld at its initial .temperature for vanV extended time interval.

My invention is not limited tothe specific dei tails of Vconstructionrthat are illustrated nor .is `the invention limited .in its 'application `to use rwith Va vessel of 'the kind described, since Vthe details may be variously `modified and the invenn. tion may-be variously appliedto vessels of theV 75 different 'kinds-used -as drinking vessels or V`as dispensers vessels, without departing from the spirit and Vscope of the invention as set forth in the appended claims. f
